A study about black holes that highlights mathematical errors from the very beginning, already mentioned by some scientists in the past, but never really considered seriously.

Another model is proposed to describe the cosmologic objects currently considered as black holes.

Chalk also supports uncertainty : https://chachatelier.fr/chalk/chalk-features.php (combined with arbitrary long numbers and interval arithmetic)

Most people didn't understand that my goal was not to benchmark all existing calculator apps. It is on purpose that I did not mention all "pretty good" softwares, because I cannot know them all.

The article I wrote wants to mention every point that should be adressed (in my opinion) to make a good calculator. Qalculate, like many others, does address some of them.

But as far as I know, only Chalk addresses all of them.

Let's say that : if you do not use arithmetic interval, at some point your floating point computations will be wrong and misleading if you do not carry information about how much bits are garbage. Chalk does that.

You can achieve that, this is a preference of Chalk about what should be the next input

RPN is just an option (provided by Chalk). The "minimalist" GUI is just the introduction of the full article. You have to reach <https://chachatelier.fr/chalk/article/chalk.html#toc-36> to go deeper into numerical problems of usual softwares.

Once again, Chalk is not the best software ever, it is just what I have to build myself to fix the problems I usually encounter. Not to say that all other softwares are equally bad, but to my knowledge, none of them will address as much limitations at the same time.

Thanks ! There were so many things to say that I was afraid nobody would read up to the end. GUI is only the visible part of the iceberg. Number representation (to keep exact values), accuracy, interval arithmetics... are hard to introduce in the first place.

Thanks, I have added some more "mobile compliant" CSS styles.
